[Exist-open] newbee musings

[Hungerburg <pc...@my...>]

Happy Hackers,

I wanted to output json that is readily consumable by dojo-data, and 
eXist made this a quick adventure. code below, for any other newbees 
that struggle with xquery.

Now if only I could get eXist to enforce uniqueness for the id attribute 
of all documents in namespace "produkt" below the "data" directory in my 
application. I'd rather not manage uploads by a controller, but 
preferred to upload via webdav or http put. I toyed around with triggers 
to some success. any ideas on this?

########### code/
(: find all products with a matching @code,
    return some dojo-data consumable json :)

let $hits := collection($coll)//produkt:produkt[ft:query(@code, $query)]
let $count := count($hits)

let $result :=
   <result>
     <identifier>id</identifier>
     <label>titel</label>
     <count>{$count}</count>
     {
       for $item in $hits
       return
       <items>
         <id>{string($item/@id)}</id>
         <code>{string($item/@code)}</code>
         <titel>{string($item/produkt:titel1)}</titel>
       </items>
       }
   </result>
return

json:xml-to-json($result)
########### /code

Thank you
